Description

Technical Field

[0001] The utility model relates to the technical field of clamping, in particular to a flexible plate clamping device. Background Art

[0002] The general operation of punching is: first lay the material to be punched on the operating table, and the worker holds the punching equipment to punch the material. This punching method is suitable for materials with smaller sizes, but not for materials with larger sizes. For example, for a flexible board with a length and width of 120cm*60cm, if it is still punched according to the above punching method, there are many problems: ① The worker stands on one side of the operating table and punches holes at multiple preset points of the flexible board. Due to the large size of the flexible board, the farther away from the position of the worker, the more inconvenient it is to punch, which may cause the holes to be crooked; ② There are many points on the flexible board that need to be punched, and the worker always keeps his head down when punching. This posture is very tiring over a long period of time. Therefore, this scheme provides a flexible board clamping device for placing the flexible board vertically and clamping it.

[0003] In order to solve the deficiencies in the prior art, the utility model provides a flexible board clamping device, which can clamp and fix a vertically placed flexible board.

[0004] In order to achieve the purpose of this utility model, the following scheme is proposed:

[0005] A flexible plate clamping device comprises a base and two clamping structures arranged opposite to each other.

[0006] The clamping structure includes two clamping plates, a limit box and a linear stroke component. The limit box is arranged on the top of the base. One side of the limit box is opened and two columns are arranged inside. The two clamping plates are arranged between the two columns, and the clamping plates are rotatably connected to the corresponding columns. The side of the clamping plate away from the limit box extends to the outside of the limit box for clamping the flexible plate. The other end of the clamping plate is connected to the inner wall of the limit box through a number of springs. The linear stroke component is arranged in the limit box and is connected to a push rod. The push rod is located between the two clamping plates and is used to adjust the opening and closing angles of the two clamping plates when the push rod moves.

[0007] Furthermore, the clamping plates are arranged to be a V-shaped structure with an obtuse angle, and the angles of the two clamping plates are arranged to face outwards.

[0008] Furthermore, a plurality of grooves are sequentially arranged from top to bottom on one side of the clamping plate away from the limit box.

[0009] Furthermore, the limit box is provided with a plurality of U-shaped plates from top to bottom in sequence. The U-shaped plates are arranged horizontally, and their U-shaped grooves open toward the limit box. The U-shaped plates are located in corresponding grooves, and the U-shaped plates are used to abut against the end surface of the flexible plate.

[0010] Furthermore, it also includes a position adjustment mechanism for adjusting the position of one of the clamping structures.

[0011] Furthermore, the position adjustment mechanism includes a slide plate, a screw rod and a handwheel. The base is provided with a slide groove running through it, and a support seat is provided on the top of the base. The slide plate is arranged as a U-shaped structure.

BRIEF DESCRIPTION OF THE DRAWINGS

[0014] Figure 1 A structural diagram of the clamping device is shown;

[0015] Figure 2 A top view of the internal structure of the limit box is shown;

[0016] Figure 3 A front view of the clamping structure is shown. DETAILED DESCRIPTION

[0017] like Figure 1 As shown, this embodiment provides a flexible board clamping device, including a base 1 and two clamping structures 2 arranged opposite to each other.

[0018] Specifically, Figure 1 , Figure 2As shown, each clamping structure 2 includes two clamping plates 21, a limit box 22 and a linear travel component 23. The limit box 22 is arranged on the top of the base 1, and one side of the limit box 22 is opened. Two columns 221 are arranged inside the limit box 22. The two clamping plates 21 are symmetrically arranged between the two columns 221. The clamping plates 21 are rotatably connected to the corresponding columns 221 through a plurality of sleeves. The side of the clamping plate 21 away from the limit box 22 extends to the outside of the limit box 22 for clamping the end of the flexible plate. The other end of the clamping plate 21 is connected to the end of the flexible plate 22. A number of springs 25 are connected to the inner wall of the limit box 22, and a linear stroke component 23 is arranged in the limit box 22. The linear stroke component 23 is connected to a vertically arranged push rod 24. The linear stroke component 23 is used to move the position of the push rod 24. There are many ways to implement the linear stroke component 23, such as using a telescopic rod driven by a cylinder, an oil cylinder or a hydraulic pressure. The push rod 24 is located between the two clamps 21. When the push rod 24 moves, it is used to adjust the opening and closing angles of the two clamps 21, thereby utilizing the two clamps 21 to clamp the flexible plate.

[0019] Regarding the shape of the push rod 24:

[0020] The first case: the horizontal cross section of the push rod 24 is a trapezoid, the larger side of the bottom surface of the push plate 24 is connected to the linear stroke component 23, and the smaller side of the bottom surface is inserted between the two clamping plates 21. Figure 2 From the perspective, when the linear stroke component 23 is used to move the push plate 24 further to the right, the clamping plate 21 will be prompted to rotate, thereby reducing the distance between the right sides of the two clamping plates 21, thereby achieving the purpose of clamping the flexible plate. When the flexible plate needs to be released, the linear stroke component 23 is used to move the push plate 24 to the left, and the clamping plate 21 is reset under the action of the spring 25, thereby expanding the distance between the right sides of the two clamping plates 21 to facilitate the removal of the flexible plate.

[0021] The second case: the horizontal cross section of the push rod 24 is circular. In this case, the clamping plates 21 need to be set as a V-shaped structure with an obtuse angle, and the angles of the two clamping plates 21 are both set outward.

[0022] In order to improve the stability of the splint 21 during the opening and closing process, and to facilitate the staff to quickly determine the position of the flexible board, this embodiment adopts the following measures: Figure 1 , Figure 3 As shown, a side of the clamping plate 21 away from the limit box 22 is provided with a plurality of grooves 211 from top to bottom, and the limit box 22 is provided with a plurality of U-shaped plates 26 from top to bottom. The U-shaped plates 26 are horizontally arranged, and their U-shaped grooves open toward the limit box 22. The U-shaped plates 26 are matched in the corresponding grooves 211. The U-shaped plates 26 can be used to abut the end face of the flexible plate so as to quickly determine the position where the flexible plate is placed.

[0023] Here is a point to explain. Figure 3From this perspective, for ease of description, the three inner walls of the groove 211 are named the upper wall, the lower wall and the left wall, respectively. The top and bottom surfaces of the U-shaped plate 26 are respectively close to the upper and lower walls of the groove 211, but the U-shaped plate 26 is not close to the left wall of the groove 211. A certain space is left between the U-shaped plate 26 and the left wall of the groove 211 to prevent obstruction to the opening and closing of the splint 21.

[0024] In order to make the device applicable to flexible boards of more specifications, the present embodiment adopts the following measures: Figure 1 As shown, the device also includes a position adjustment mechanism for adjusting the position of one of the clamping structures 2, the position adjustment mechanism includes a slide plate 31, a screw rod 32 and a hand wheel 33, the base 1 is provided with a slide groove 11 that runs through it, the top of the base 1 is provided with a support seat, the slide plate 31 is set as a U-shaped structure, the horizontal section of the slide plate 31 slides in the slide groove 11, the vertical section of the slide plate 31 is fixedly connected to the limit box 22, one end of the screw rod 32 is rotatably connected to the limit box 22, the other end of the screw rod 32 passes through the support seat and is connected to the hand wheel 33, and the screw rod 32 is threaded with the support seat. When the spacing between the two clamping structures 2 needs to be adjusted, just turn the hand wheel 33.

[0025] In order to improve the punching quality, in actual application, a support plate can be set on the back of the flexible board to provide support for the flexible board during the punching process. This part does not belong to the technical problem to be solved by this solution and will not be elaborated here.

[0026] The above embodiments are only used to illustrate the technical ideas and features of the utility model, and are not intended to be the only or limit the utility model. Those skilled in the art should understand that various changes or equivalent replacements made to the utility model without departing from the scope of the utility model are within the scope of protection of the utility model.
